Final answer:
Nonpolar molecules do not have dipole-dipole intermolecular forces with other nonpolar molecules; this statement is false. Instead, they experience London dispersion forces, which result from temporary, induced dipoles.
Step-by-step explanation:
The statement that nonpolar molecules have dipole-dipole intermolecular forces (IMFs) with other nonpolar molecules is false. Nonpolar molecules do not have permanent dipoles and therefore cannot engage in dipole-dipole interactions. Instead, they interact with each other through London dispersion forces, which are temporary, induced dipole-induced dipole interactions.
Polar molecules, on the other hand, do exhibit dipole-dipole interactions because they have permanent dipoles. These molecules have a region with a slight positive charge and another with a slight negative charge, enabling them to attract other polar molecules through their opposite charges. The London dispersion forces are also present in polar molecules, but they are generally weaker compared to the dipole-dipole interactions in small polar molecules.
